Sustainable Breakthrough in Greenhouse Gas Conversion

Posted by Marketing Team on

In a massive step toward sustainability, researchers at McGill University have identified a chemical process that could significantly reduce greenhouse gas emissions–with such brilliance the use of sunlight to turn two of the most prominent greenhouse gasses–methane (CH₄) and carbon dioxide (CO₂)–into materials worth using. The novel process may prove beneficial to industrial uses and the environment and underscores the crucial role that science has to offer in fighting climate change across the world.

 

Sunlight-Powered Green Chemistry

From the findings under Nature Communications, the said discovery is analogous to how photosynthesis works—where the plants produce glucose and oxygen from the conversion of CO2 and H2O to methane and CO2 are transformed into methanol and CO—all under the help of sunlight and catalyst. The generated green methanol can be used to produce fuel and plastics while carbon monoxide obtained is useful in several industrial processes. Notably, it does not involve the use of strong chemicals and also, the energy source from the sunlight making the completion energy efficient and environmentally friendly.

The process is initiated with the synthesis of the photocatalyst which involves the deposit of gold, palladium and other metals combined with gallium nitride. This mixture was then transferred into a quartz reactor and subjected to simulated sunlight using a Xenon lamp. Under these conditions, the catalyst provided the opportunity for the interaction of methane and carbon dioxide wherein an oxygen atom of the carbon dioxide binds to methane and forms green methanol and carbon monoxide. These gasses were subsequently characterized by other high-scale methods such as gas chromatography (GC) and nuclear magnetic resonance spectroscopy (NMR).

 

The reaction takes place under mild conditions and the energy source employed here is the most abundant natural solar energy. This is a scalable and sustainable approach to solar power incorporation and catalysis making the process a promising one in repurposing greenhouse gasses.

 

The Role of Catalysts: How They Power Chemical Reactions

Catalysts are crucial in driving chemical reactions more efficiently by lowering the energy required for the reaction to occur. They establish a reaction pathway that requires lower energy; a high-energy reaction is made available to proceed. McGill's study showed that the gold, palladium, and gallium nitride catalysts were at the core of the reaction that enabled the conversion of methane and carbon dioxide into methanol. Catalysts work without becoming part of the reaction products and that means the process can be repeated as long as the catalyst is in contact with sunlight.

In this study, the researchers prepared metal catalysts including platinum, palladium, gold and rhodium through in situ chemical reduction and colloid immobilization approaches. These catalysts were able to selectively coordinate methane and carbon dioxide molecules so that these could react under relatively less severe conditions than in the usual methane/carbon dioxide conversion reactions. Catalyst helps in getting the requisite energy from the light source for converting the object of reaction making it economically viable as well as ecological.
